Growing Barleria lancifolia

Barleria lancifolia seedlingsBarleria lancifolia is propagated either by seed or cuttings.

Seed: To prevent seed loss collect the seed as soon as the seed capsules turn brown.

Plant the seed in a mixture of equal parts of river sand and good soil. Place the tray in a shady spot and water well once a week. Ideal soil and air temperature for optimal germination is between 20 and 28 °C. Transplant the seedlings in separate pots when they are more or less 100 mm high.

Cuttings: Take softwood cuttings, 120 mm in length, dip in a hormone powder and plant them in a mixture of equal parts of good soil and river sand. The best temperatures for rooting cuttings are between 20 and 30 °C. Place the container with cuttings in a cool shady place and water well twice a week. Transplant the rooted cuttings into a good soil mixture (after 3–5 months).

Pests and disease: There are no known pests or diseases that attack Barleria lancifolia.
